Smoker needs to be completely versatile. Cold smoke and hot smoke capable. It needs to be big as my family does 700 to 1400 lbs of venison sausage every year so it has to hold a lot of meat. Smoker needs to be relatively easy to use. I am not afraid to spend a few bucks on proper components and controls no sure where to get. I live in Alberta, canada.
Here are the materials I have to work with so far:
Walk-in style cooler box insulated sandwich panels. I plan to build the main box with this material. Size will be approximately 60" long 47" high 36 inches wide(deep). I have an old BBQ that works good and was thinking of attaching to main box as a smoke generator. I have a 120v fan/heat coil into to provide heated circulation. I think I want to use 220 oven element but not sure how to acquire and wire all the controls needed and don't know if it will provide enough heat to get to desired hot temps 325F.
I will post more on my ideas including sketches when I get a chance. Look forward to the advice from here.
